Delta Cancri (δ Cnc / δ Cancri) is an orange giant star approximetaly 136 light-years away in the constellation Cancer. It has the traditional name Asellus Australis which in Latin means "southern donkey". Since it is near the ecliptic, it can be occulted by the Moon and very rarely by planets.
In 1876, the possibility that Delta Cancri has a companion star was proposed [1].
